Charcot is a condition associated with diabetes. A symptom of diabetes is loss of nerves in the feet which inhibits the sensation of pain, such as from an injury. This nerve damage is called diabetic neuropathy, and with it comes an increased risk of bone fractures. A fracture may go unnoticed and continued use of the injured foot may lead to impaired healing and deformity.
Early signs of Charcot can be calluses or foot ulcers over bony prominences of the feet which are out of alignment. Again, if you have diabetic neuropathy, failure to sense pain and failure to routinely inspect your feet for problems can lead to serious harm including infection.
Once Charcot is detected, immediate medical treatment is required. The foot may be put in a splint or cast to help relieve pressure, which can take many months. If the foot does not heal over time, surgery to correct the deformity may be recommended.
